FLASH-LIGHT.

Specification of Letters Patent.

Patented Jan. 2, 1912.

Application filed April 29, 1910, Serial No. 558,352. Renewed May 23, 1911. Serial No. 629,062.

To all whom it may concern:

Be it known that we, LIBERTY K. FLANA- GAN and CHARLES A. MILLER, citizens of the United States, both residing at Moberly, in the county of Randolph and State of Missouri, have invented certain new and useful Improvements in Flash-Lights, of which the following is a specification.

This invention relates to flash lights and more particularly to that class of flash light especially designed for use in taking photographs.

The object of the invention is to provide a flash light, the construction of which is such that the torch may be adjusted vertically of the sup orting stand and the powder spread on the flame b air pressu e.

A further 0 ject 18 to rovide a flash light including a plurality of telescopic sections, one of which is provided with a powder receiving receptacle and a laterally extending arm adapted to support a torch, means being provided for forcing a current of air through the telescopic sections into the powder-receiving receptacle for spreading the powder on the torch,

A still further object of the invention is generally to improve this class of devices, so as to increase their utility, durability and efiiciency.

Further objects and advantages will appear in the following description, it being understood that various changes in form, proportions and minor details of construction may be resorted to within the scope of the appended claims.

For a full understanding of the invention and the merits thereof, reference is to be had to the following description and accompanying drawings, in which:

Figure 1 is a side elevation of a flash light constructed in accordance with our invention; Fig. 2 is a vertical ectional view of a portion thereof; Fig. 3 is a detail perspective view of the spreading nozzle detached; Fig. 4 is a side elevation illustrating a modified form of the invention.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The improved flash light forming the subject matter of the present invention comprises a supporting stand 5 having a tubular member 6 rigidly secured thereto and in which is slidably mounted a plurality of telescopic sections 7 constituting a collapsiblc standard, as shown. Fastened in any suitable mannerto the upper telescopic section of the standard, is a cup or receptacle 8 adapted to contain a quantity of mag-- nesia or other material, said receptacle being provided with a removable cover 9 to which issecured a cap piece 10 having a laterall extending arm 11, said cap and arm being provided with intersecting passages, as shown. Secured to the upper telescopic section of the standard beneath the receptacle 8, is a support ng arm 12, to the free end of which is secui ed in any suitable manner, a torch 13, the latter being provided with a vertically disposed concavo-convex guard or shield 14. Engaging the free end of the arm 11, is a discharge nozzle 15 through which the magnesia or powder in the receptacle 8 is delivered to the torch 13. The nozzle 15 comprises a tubular body portion, the free end of which is flattened at 16 and provided on its lower side with a longitudinally disposed discharge slot 17 for directing the powder into the path of the flame. Seated in the bottom of the receptacle 8, is a nipple 18, the lower end of which is projected within the adjacent telescopic section 7, while the upper end thereof is bent downwardly in spaced relation to the bottom of the receptacle, as indicated at 19. Connected within the projecting end 20 of the nipple 18, is one end of a hose or other flexible conductor 21, which latter extends through all of the telescopic sections 7, the lower end of the conductor being connected with a valve 22 on an air tank 23. Disposed within the air tank 23, is a pump 24, the handle 25 of which projects above the top of the tank so that by closing the valve 22 and operating the handle 25, said tank may be filled with air. Each telescopic section 7 is provided with a screw or similar fastening device 26, which latter bears against the adjacent telescopic section and serves to lock said sections in either extended or retracted position.

In operation, the valve 22 is closed and the tank 23 pumped full of air. The telescopic sections 7 are then extended until the torch 13 has been adjusted to the proper height, after which the clamping screws 26 are tightened which holds the sections against accidental movement. After the torch 13 has been lighted, the valve 22 is moved to open position, thus allowing a current of air to pass through the conductor 21 and nipple 18 into the receptacle 8, the magnesia or other material in said receptacle 8 being forced upwardly and laterally through the nozzle 15 and discharge orifice 17 in the path of the flame from the torch, thus to produce a flash light. By releasing the clamping screws 26, the telescopic sections may be housed within the lower section 6 so as to permit the device to he compactly nested or transportation or shipment.

In Fig 4 of the drawings, there is illustrated a modified form of the invention, in which the standard 7 is formed of a single section, and supported directly on the air tank 23, there being a tube 27 communicating with the interior of the tank at the top thereof for connection with an air pump, the construction and operation of the device being otherwise similar to that shown in Figs. 1 and 2 of the drawings.

Having thus described the invention, what is claimed as new is:

1. A flash light including an extensible standard formed of a plurality of telescopic sections, a powder receiving receptacle carried by one of the standard sections and provided with an overhanging nozzle, a torch supported by the standard, a nipple disposed within the receptacle, and a conductor extendi through all of the standard sections an having one end thereof connected with said nipple and its other end projecting through the bottom standard section and communicating with a source of compressed air for forcing air within the receptacle, thereby to direct the powder into the path of the flame from the torch.
